In the accompanying drawing, whichis made the full size of the vent,Figure I is a vertical section through the valve, air-passages, andstop-cock. Fig. II is a plan view with the cover removed, showing thevalve and airpas sages. Fig. III is a-side elevation.

Like letters of reference designate like parts in each of the figures.

A is the body of the vent, which is cast hollow, and is provided with atapering part, B, to enable it to be used in spigot-holes of diiierentsizes. The hollow neck C communicates with the air-tight chamber abovethrough airpassages b b b.

Iand II. gis a valve-seat formed in the airtight chamber G, and isprovided with a valve, g. H is a stop-cock of ordinary construction forclosing and preventing the passage of air into the eask when it is notrequired. The air is admitted through this cock and opening-h into thevalve-chamber t', when. it raises the valve and passes through theopenings b b b and hollow neck C into the cask, as shown by the arrowsin Fig. I, to occupy the space made vacant by the drawing ofi' of theliquid.

The object of the invention is to make, at a moderate cost, a vent forbeer and other casks, which can be easily cleaned, and one that shall besuficientlystron g and compact to withstand the hard usage to which itmay be subjected.
